Undoubtedly, the aluminum disc, the aluminum alloy in the future will be more widely used, the aluminum metal ranked second in the current use of metal in the world, after steel, it has become the second largest metal Application.The people why it is widely used is that Aluminum has characteristics that other metals do not have.

The first is the light weight of aluminum and the ability to resist corrosion. These two points are the most notable characteristics of aluminum discs. It has a small density and light weight, so it is widely used in aviation, automobile and ship transportation. In addition, high point industries such as spacecraft and artificial satellites also use a large amount of aluminum disc and aluminum alloys.

 Second, it has excellent electrical conductivity. Although its conductive capacity than gold, silver and copper to conductivity is weak, but due to its large reserve, and the density is small, only about one third of copper, thus transporting the same amount of electricity, quality of aluminum is only half of copper.In addition, the surface of the aluminum oxide film not only has the ability to resist corrosion to some extent of insulation, so that round piece of metal aluminum in the electrical manufacturing industry , wire and cable, and the radio industry has a very wide range of uses.

Finally, the malleability of aluminum:. Aluminum disc and aluminum alloy in the industry is often used as a forge, can launch all kinds of shapes with varieties of forged parts, cohesion and can use a variety of measures, including the use of fusion welding, also Resistance welding welding methods, such as binder and riveting and screwing to cohesive machinery, can be used.Other hot aluminum agents are also used to melt refractory metals and welded steel rails and can be used as deoxidants in the process Steel fabrication.
